Problems solved by technology

[0019] Therefore, the moving distance from the retracted position of the rotating roller 55 to the working position contacting the sleeve W is long, it takes a long time to move the rotating arm 57 forward and backward, and there is a problem that a single measurement time becomes longer.

Embodiment Construction

[0039] Embodiments of the present invention will be specifically described below with reference to the drawings.

[0040] figure 1 It is a schematic configuration diagram showing the main parts of the bushing eccentricity measuring device of the present invention, figure 2 Construct a diagram for it as a whole.

[0041] figure 1 and figure 2 It shows the sleeve tube eccentricity measurement device 1 of the present invention, along the substantially horizontal photographic optical axis Z from the light source 2 to the camera 3, a V-shaped groove 4 for placing the sleeve tube W is formed, so that the rotating roller 5 contacts the V-shaped groove 4 placed there. While rotating the ferrule W, the end face can be photographed by the above-mentioned camera 3 to measure the eccentricity of the optical fiber insertion hole 6 and the eccentricity of the optical fiber core attached to the ferrule.

[0042] The casing eccentricity measurement device 1 has a casing rotation mecha...

Abstract

This device is provided with the rolling roller on the tip side of a biaxial slide table arranged movably in the front-to-back direction and in the vertical direction of an imaging optical axis, and is equipped with a table driving mechanism for advancing the rolling roller from a backward retreat position of the imaging optical axis to a just overhead part of the V-groove and lowering it from the advance position to a work position in contact with the ferrule.

Description

technical field [0001] The present invention relates to a sleeve eccentricity measurement device for measuring the eccentricity of an optical fiber insertion hole formed in the sleeve and the eccentricity of an optical fiber core mounted on the sleeve. Background technique [0002] The ferrule is installed on the front end of the optical fiber as a component of the connector of the optical fiber to protect and center the end. It has a tubular shape with an insertion hole for the optical fiber in the center or a flanged type with a flange in the center or on one side of the tube. Wait. [0003] For example, a ferrule for a single-mode optical fiber with a cladding diameter of 125 μm has an outer diameter of about 1.5 to 2.5 mm, and an optical fiber insertion hole with an inner diameter of about 126 μm. [0004] When using this ferrule for optical connection, after polishing the end face of the ferrule installed at the front end of the fiber for each optical fiber, insert the...
